Part 1: Research Boot Methods

Part 2: Access BIOS / UEFI

Part 3: Use a bootable USB media

Background / Scenario

The most common method to install an operating system on a new computer requires bootable media, such as DVD or USB. In this lab, you will investigate different ways to install windows: with and without bootable media.

To change the boot order on your system, you will need to access Unified Extensible Firmware Interface (UEFI) or the legacy Basic Input Output System (BIOS).

UEFI is the software that is designed to replace the legacy Basic Input Output System (BIOS). The UEFI comes with additional benefits, such as improved security, faster boot times, and large capacity hard drive support.

The Basic Input Output System (BIOS) is the low-level software that is located on one of the chips of the motherboard. The BIOS is responsible for essential functions, such as booting and keyboard control. The BIOS also configures the hard drive, CPU and memory and other related equipment.

Required Resources

Internet access
A computer where the BIOS or UEFI is accessible
A USB flash drive with a minimum of 8 GB


Part 1:Research Boot Methods

A few of the available boot methods are USB optical media, USB flash media, and Preboot Execution Environment (PXE) network and internet-based, hard drive partition. In this part, you will review the process to create a bootable USB and optical media, use a network boot, and boot from a hard drive partition.

Perform an internet search to answer the following questions.


Bootable USB and optical Media

What is the process to create a bootable USB or optical media?

Type your answers here.

For Windows, you will need to download or purchase a copy of the Windows operating system from a authorized source, such as the Microsoft website. At the Microsoft website, tools and directions are provided to create a bootable media to install Windows on your current PC or a different PC. For the other operating systems, such as Ubuntu Linux, you can download the OS from the Ubuntu website and write the OS onto a USB or optical media and make sure it is set to be bootable.

PXE and Internet-Based Boot

PXE boot is a process where the device boots from its NIC.


Where would you use PXE boot?

Type your answers here.

PXE boot is usually used in a data center infrastructure environment to deploy software.

What are the components required for a PXE boot?

Type your answers here.

On the client side, the PC must have a partition on a hard drive to store temporary files and a PXE-capable NIC that supports Wake-on-LAN mode connected to the same wired network. The PXE boot server requires DHCP services to provide clients with IP network configuration to join the network and PXE configurations or direct the client PC to a server with the necessary boot files.

What are the advantages and disadvantages of using PXE boot?

Type your answers here.

Answers will vary. For example, PXE boot can simplify the deployment process by automating the maintenance and installation of multiple systems over the network without inserting optical or flash media into each system. With PXE boot, the client system does not require an operating system on the hard disk. In the event of hardware or software failure, this allows the administrator to troubleshoot the issue and fix the problem. However, it takes technical knowledge to deploy a PXE server.

What is an Internet-Based Boot?

Type your answers here.

Internet-Based boot is similar to PXE boot. The installation server is located on the internet. The local DHCP server supplies the DNS name of installation server, similar to downloading updates and additional packages.

Hard Drive Partition

After the operating system has been successfully installed on a hard drive partition, the bootable hard drive partition should be configured as the default boot device.


Under what circumstances would you boot to another internal hard drive partition?

Type your answers here.

Answers may vary. You may want to boot the recovery partition to restore the operating system to factory defaults or troubleshoot issues. The system may have multiple operating systems installed on different partitions, such as Windows and Linux.

Part 2:Access BIOS / UEFI

BIOS / UEFI firmware allows you to change the advanced settings. Within the BIOS / UEFI firmware, you can change the boot order. There are two ways to access BIOS / UEFI: settings or boot keys. You should only access the BOS / UEFI when necessary.

Note: Be careful when accessing motherboard firmware. Incorrect firmware settings can prevent your computer from starting.

Step 1:Enter BIOS / UEFI using boot key options

You could use the boot key sequence to access the motherboard firmware settings if you have an older device that uses legacy BIOS or no access to Windows 10 computer.

a.Restart the computer if you have access to a computer.
b.When the splash screen displays, press the key combination. Press the required key combination until you enter setup mode. The key combination usually consists of ESC, Delete or one of the Function keys, such as F12.


What is the key sequence you used to access the motherboard firmware?

Type your answers here.

Here are some computer brands and their respective keys to access the motherboard firmware:

Dell: F2 or F12.

HP: ESC or F10.

Acer: F2 or Delete.

ASUS: F2 or Delete.

Lenovo: F1 or F2.

MSI: Delete.

Toshiba: F2.

Samsung: F2.

Surface: Press and hold volume up button.

c.If the boot process finished too quickly, restart the device again and press the same key sequence again until you have successfully entered the firmware settings.
